KeyUnity KF03 Titanium Nano Flashlight, LR44 Button Cell 100 Lumens 5W LED Keychian Flashlight for Everyday Carry (KF03 Sandblasted)

Great small 1 AAA battery light. Only one brightness but for the money and the size and seeming quality it is a great little torch.

Perfect keychain light

Nice size and slim build.

Simple, small, and way brighter than expected. This is a perfect keychain add on, and coming with extra batteries is a huge plus. I've already used it a handful of times and it's simple and efficient. Highly recommend picking this up, and it'd be a great gift for anyone!

Because of its size, it takes a little practice, but it works beautifully!

The product is too small (although it was referred to as “mini”) and its dimensions should have been advertised. Unfortunately, the product is not working and it’s too much of a problem to return it. I give it a failing grade.

The KF03 build quality is great. Small size and light weight. Smooth turning action. Very bright for the size. I believe at this size this is the best keychain light on the market. I wish these were USB-C rechargeable and had two brightness settings but you won't find that on a light this small as of the writing of this review. I also have a KF00 which is the smaller, less-bright version of the KF03. The first KF00 I received was faulty and I could only get it to flash on about a quarter second at a time if I turned it just right but the replacement worked fine. Acceptable failure in my opinion since I've now purchased about 10 different products from this company and this was the only defect.

Truly well made. Slick and beautiful and easy to use. The thing that makes it great-it’s size- is also its downfall. It uses tiny batteries that are probably not powerful and don’t last long. So this flashlight it probably best used to keep on your keychain for those times you need to find the lock on your door on a dark night. It isn’t very bright. Sure it’s probably because of its size right. Well, I bought a different one soon after for $8 that’s even smaller than this one and uses the same kind and amount of batteries yet it was a bit brighter. That said, the price tag for what you get with this one is a bit high. So you’re paying for the look not the function.
